- Consider the given reaction in which NC−NC− is the nucleophile and CH3CNCH3CN is the solvent. The reactant molecule has a structure with solid and dashed wedge bonds. A solid wedge () is used to show the bond that is above the plane of the paper, and a dashed wedge () is used to show the bond that is behind the plane of the paper. Draw the product of the following reaction:arrow_forwardFor the following reactions, choose if the arrows indicated are correct or incorrect.arrow_forwardHow much free energy is released under standard conditions when electrons are passed from succinate to ubiquinone? Note: The Faraday constant F = 23.1 kcal/(mole x volt) A) About 0.069 kcal/mol B) About 54 kcal/mol C) About 35 kcal/mol D) About 1.6 kcal/mol E) None of the above, energy is required for electrons to flow from succinate to ubiquinonearrow_forward
- Write the MAJOR product(s) for each of the following reactions. (Write only one product UNLESS the reaction has both a 1,2 and a 1,4 product). You can either write the structure(s) of the product(s)arrow_forwardWhat characterizes a pericyclic reaction?arrow_forward2. Give a strong reducing agent that can be used to reduce benzene to cyclohexane.arrow_forward
- Which product is the major and minor in a halogenation reaction with cl2arrow_forward7. The reaction of methoxide anion with bromoethane to yield the ether ethyl methyl ether and the bromide anon (Br-) is an excellent example of a general reaction type called Sy2 (substitution nucleophilic bimolecular): CH,0+ CH,СH-Br a CH3-0-CH,СH; + Br- a. Change in enthalpy is -103 kJ/mol; the change in entropy is + 0.025 kJ/mol-K. Calculate DG at 300K. b. Is the reaction endergonic or exergonic? c. Is the reaction endothermic or exothermic? d. Use curved arrows to show the complete mechanism. Reaction of 2-methyl-1-butene with H-Cl could yield TWO alkyl chloride products. Draw and name 8. them.arrow_forwardIdentify the structures of the major product or reagent in the reaction, or the structure of the compoundarrow_forward
- Select the outcome of the following reaction. Br2 Br Br only Br only Brm Br Brarrow_forwardProvide the IUPAC names for the reactant and product of the halogenation reaction shown here:arrow_forwardIn general, a catalyst speeds up the reaction and yields: O a little more product as compared to without the catalyst O substantially more product as compared to without the catalyst O the same amount of product as compared to without the catalyst O less product as compared to without the catalystarrow_forward
